TORSION-SPRING FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 239,178, dated March 22, 1881.

' Application filed January 13,1881. (ModeL) To all whom it may concern Be it known that I, THOMAS J. MAGNER, a citizen of the United States, resident at Hornellsville, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Torsion-Springs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, and to letters or figures of reference marked thereon, which form a part of this specification, in which.

Figure 1 is a cross-section. Fig. 2 is a partial longitudinal section. Fig. 3 is a plan view from below. Figs. 4, 5, and 6 are detail sections.

This invention relates to torsion-springs, es-

' pecially their adaptation to side-bar vehicles.

The invention consists in the construction hereinafted described, and particularly pointed out in the claim.

In the drawings hereto annexed, A is the head-block, B the rear axle, and O U the side bars, of a vehicle, all connected together by the clips D. At the point of connection the side bars are cut out transversely ate, and the head-block and rear axle at a,

E are metal blocks having raised portion d and perforated ends 6. These blocks are placed between the ends of the side bars and headblock and rear axle, with raised portion (1 resting in, and snugly fitting in, groove 0, and the lower portion with ends ein grooves a, and the sides of clips D passing through perforationse.

F is a torsion spring or bar, having its ends ff firmly held in plates E, there being one spring to each side bar, running under the same and held tightly at the middle by a clip, G, in whose plate 9 the spring is firmly fastened. Midway between this clip G and the ends of the spring is located a clip, H, in the plate h of which is the circular bearing h, the spring passing through such plate and being rounded in said circular bearing. Rigidly secured to spring F, upon each side of this plate ing held by clip G; or two smaller clips may' take the place of this single clip, one for each end.

As another modification, the spring F may be cut away just beyond the arm k of hanger K, which is the farthest from the head-block or rear axle, which construction only gives four torsion-springs to the vehicle, or two to each side bar.

Torsion side springs having cranks at their outer ends, fixed at their inner ends to central clips upon the under faces of the side bars, and supported near their outer ends by clips, have been used in connection with semi-elliptic springs, and protection is only asked for the specific construction hereinafter claimed.

What I claim is As an improvement in side torsion-springs for vehicles, the torsion-springs F F, having their ends fixed to the plates E E of the clips DD, and tightly held at their middles by the clips G G, and provided with the arms la 70, composing hanger K, in combination with clips H, having bearings h in their plates h, and the semi-elliptic springs L L, constructed and operatin g substantially as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS J. MAGNER.
